Ryan Phillippe to get Straight A's

Ryan Phillippe and Anna Paquin have reportedly been cast in 'Straight A's'.

Nu Image and Millennium Films had been keeping details of the comedy under wraps, but now that filming is underway in Louisiana, it has been revealed that the pair will appear in the film, along with Luke Wilson and Riley Thomas Stuart.

Ryan will play a man who has been in and out of rehab numerous times and is convinced by the ghost of his mother to try and repair his relationship with his family, who he hasn't seen for many years.

Travelling to Louisiana with few possessions other than a sack of marijuana and a bag of pills, the man confronts his older brother (Wilson) and is forced to face his sister-in-law (Paquin), who he was previously in a relationship with.

Riley will play the son of Ryan's character.

'Wonderland' filmmaker James Cox is directing the film, with Dave Cole penning the script.
